WEBBING CLAMP Filed March 14, 1933 INVENTOR ATTORNEY Patented Dec. 1933 I Theinvention relates to a webbing clamp and more particularly to mountings for interwoven strips of webbing. l Y Ordinarilyi in the use of interwoven strips'of 5 webbing or bands in furniture for supporting the seats in chairs, couches or other articlesof furniture, nails or tacks are employed to secure the webbing and due to thevarying tensioncn the webbing caused by theweight and movement of 7 n S imilar; reference characters indicate corre- 65 :spon-ding parts throughout the several views in 10 a person occupying the seat of the chair or the like, the webbing stretches and becomes loose. over a period of time and irequen'tlytears at its point of attachment or where secured or the tacl'rs'or nails are extracted oriloosened in the wooden 15.,frame V I Q The primary object of the invention is to overcome the necessity for the nailing or tacking of the webbingto the wooden frame of the article of event of a stretching thereof the said webbing may be conveniently tightened and thus assure maximum iii in the use thereof.

Another ob ect of the invention is the provision of a clamp or mounting of this character, wherein the construction thereof is novel in form and in the application of the same to furniture the webbing ordinarily employed will be firmly secured and may be conveniently and easily adjusted to take up slack or stretching, the webbing inthe mounting will be free for flexing action and without any liability of the same becoming loose or separatedin its attachment to the article of furniture and thus eliminating the use of nails or tacks as is commonly done for the fastening of the webbing to the, furniture.

v A furthercbject of the invention is the'pro vision of a clamp or mounting of this character,

which is extremely simple in construction, thoraccompanying drawing, which discloses the pre-- ferred embodiment of the invention, and pointed out in the claims hereunto appended;

Referring to the drawing in detail, A designates generally a portion of the usual wooden frame of a 'chairsea't'orthat employed in other articles of 5 strip :make-upi Each run of webbing B is" sup ported in the clamp or mounting constituting the present invention and hereinafter fully described.

) Adapted to be attached atopposite points of the frame A are substantially U-shaped bails 10 each having its end portion 11 overlapping the edge adjacent thereto of the frame'A and fastened by screws or other fasteners'l2 thereto,

while secured to the inner face of each side portion of the frame A at'rightangle's to the plane of each bail 10 are the shanks13of a pair of eye members 14, these embracing the said ball 10 inwardly of and nextito the end 11 thereof as is clearly shown in Figure 1 of the drawing;

Swingingly connected to the opposed bails 10 are the clamps C and D respectively. Theclamp .C. includesea pair of jaws l5 and 16 united through the medium of a pintle sleeve 1'7 which encircles the companion bail 10 therefor and the' jaw 16 is formed with a channel 18 to accommodate a pin 19 about which is trained the double webbing B as shown in Figure 3 ofthe drawing, the webbing B at its portion encircling the'pin '19 occupying the channel or groove 18 in the jaw 16. Passed loosely through the jaw 16 close to its free edge andthreaded in the jaw 15 are screw fasteners 20, these disposed an equidistance apart and by such fasteners the jaws can be moved toward and away from each other and when worked toward each other will firmly and securely clamp the pin 19 and the portion'of the webbing B'encircling thesame within the groove or channel 18 and between said jaws'l5 and'16 of the clamp C. V.

The clamp D comprises a pair of jaws 21 and 22 V i 23 which encircles the companion bail 1,0 and grooves or channels 24 for a pin-like roller 25 about which encircles a portion of the webbing B, which encircling portion and the roller 25 being adapted to lie within the grooves or channels 24 with the webbing B folded on itself between the jaws 21 and 22, while loosely engaged in the jaws 21 and 22 beyond the longer edges of the webbing B and close to the groove 24 are retaining studs 26 against'which works the roller 25 when the jaws 21 and 22 are spread apart so that the webbing B can be drawn upon or free- 1y pulled about the roller 25 for the tightening of said webbing to take up slack or any stretched condition present therein. Loosely passed through the jaw 22 and threaded into the jaw 21 are screw fasteners 27 which serve to draw the jaws together and fasten the webbing B in the clamp D without any liability of slippage or the loosening of the webbing in the clamp, it being understood of course that the fasteners 27 are removed when it is desired to render the webbing taut or relieve the stretched condition thereof. 7

The clamps C and D in their connection with the bail 10 have a hinge action resultant from tension thereon when the seat is occupied by a slack and to render such webbing taut.

. The studs 26 each is formed with terminal heads 28 and the same being of a length to permit the spreading of the jaws 21 and 22 suf ficiently for the adjustment of the webbing B about the roller 25, the heads 28 preventing the separation of the studs 26 from the jaws as will be apparent.

What is claimed is:

1. A clamp of the character described comprising a bail adapted to be fastened to an article of furniture, eyes engaged with the bail and adapted to be secured at right angles to the plane of the bail to the article of furniture, a pair of jaws, a pintle sleeve uniting the jaws and loosely engaged about the bail, a roller-like pin seated between the jaws and adapted to have encircling the same a webbing when folded on itself about the pin for the confinement of the webbing between the jaws, and means for bringing the jaws toward or away from each other and located near the free edges thereof.

2. A clamp of the character described comprising a bailadapted to be fastened to an article of furniture, eyes engaged with the bail and adapted to be secured at right angles to the plane of the bail to the article of furniture, a pair of jaws, a pintle sleeve uniting the jaws and loosely engaged about the bail, a roller-like pin seated between the jaws and adapted to have encircling the same a webbing when folded on itself about thepin for the confinement of theweb- '10-5 bing between the jaws, means for bringing the jaws toward or away from each other and located near the free edges thereof, and terminal headed studs loosely carried by the jaws and located beyond the outer edges of said webbing 110 for the contact of the roller-like pin with sai studs on the spreading of the jaws.
